There are several on or just off of S. Congress, mostly boutique hotels. The exception is the South Congress Hotel, a full-service hotel right in the middle of the S.Congress activity. Boutique hotels include the Austin Motel, a 50s style motel that has been renovated; the Hotel San Jose; a motel renovated to a modern rock style; Kimber Modern, about 1 block off of S.Congress; and Hotel St.Cecelia, about 2 blocks off of S.Congress. There are a few B&Bs and any number of short-term rentals, often homes, that are closer than the downtown hotels. Other places listed in earlier responses are NOT on S.Congress - Driskill, Embassy Suites, Staybridge, Wood Spring and Omni.

Every Wed-Sunday there is free live music at Guero's on S Congress. Every Sunday there is free music at Jo's Coffee shop, just down the street from Gueros. At various times of the year, you can find free music at auditorium shores. If you google "free music in Austin" you can find all kinds of cool, free, fun stuff in Austin.

I'm in Austin now and Uber is here

When I went, I had trouble finding parking. There is the back angled parking mentioned, but it was all full when I got there--it can get very crowded! I was able to find parking on a street parallel a few blocks back, but you might have difficulty if this is too much walking for you.

It looks like there are at least two - Tenoverton and River Spa - but I have not been to either.

I would always call first, some of the stores are not open on Sundays or they close early. Give them a call, most of the stores are soo very nice they will be glad to answer any question you have.

If you get there early, you can park in the lot next to the newspaper building on the south side of the bridge.
